I think it's worth testing. From the logs that I could gather,
this function was already there in 1992 (!) but it's not entirely
clear that it was for AIX.  But, right now, I'd have a hard time
believing that it would be for any other kernel but AIX (the other
ones I can see are (Linux, *BSDs).

The oldest AIX we have now at AdaCore is 5.2. I'm wondering if Ulrich
might have access to something a little older?
